We were merely freshmen. I was 14 when between passing periods someone said there was a hostage situation at nearby Columbine High School. I went home and watched the scene unfold. Flipping between news channels, I watched video of kids my age running from their school and flashes of parents? tearful fearful faces.
In the following weeks we learned about the shooters and the ?trench coat mafia.? The word Columbine became synonymous with ?school shooting,? a term that had yet to be coined. To reclaim their name Columbine High launched a bumped sticker campaign: ?We are Columbine.? Thirteen years of school shootings later: We are all Columbine and we need to start seeing it that way.
Pundits point fingers but lost in the debate of where to lay blame is a deeper conversation about a comprehensive solution.
Gun enthusiasts argue that people this determined will find a way to cause destruction with or without gun control and that it is our job to get dangerous people off the streets. I would argue that it is a lot easier to control guns, than people, and the least we can do is get the guns off the streets, especially semi-automatic and assault weapons.
Most of the guns used in mass killings were purchased legally. The summer of the Aurora shooting, the shooter bought a Remington Model 870 shotgun, a M&P15 semi-automatic rifle, a Clock 22 pistol and ordered 3000 rounds for the M&P15, two magazine holders and a Blackhawk Urban Assault Vest online. The Aurora shooter was rejected from a gun club and the Connecticut shooter was denied when he tried to purchase a gun, but no matter, guns are so easy to come by. The Littleton shooters had a girl buy their guns.
Jails are not mental health facilities and mental health facilities are not jails. We hear people say, ?Well, that kid should have been institutionalized.? This suggests we should ?institutionalize? all smart depressed unaffected high-school loners. The fear of being institutionalized and the ?crazy bin? stigma contributes to avoidance of mental health services, not to mention to rights and dignity of people with mental health problems. Let?s not make villains out of victims of mental health.
Mental health services are not available to all who seek treatment. Not only is mental health considered a pre-existing condition (which makes it challenging to become insured) there are restrictions on mental health benefits. There are exclusions for substance abuse as well as annual limits on the number of mental health visits and on the dollar amount that would be covered.
What about the uninsured? A 19-year-old male in Aurora who grew up one block from the apartment of the Batman cinema shooter came to me seeking a referral for mental health services. He had recently acted violently and wanted to understand why he reacted that way. He was referred to a group therapy session for teens with substance abuse problems though he was sober during the assault and does not abuse drugs or alcohol. He did not find what he was looking for in Aurora and is still not in treatment.
We blame the parents. A few years ago I ran into a parent from my high school. She told me how worried she was about her 22-year-old son who had been diagnosed with bipolar disorder. She said, ?It?s only a matter of time before we lose him.? She did everything within her legal power to take care of him. Because he was over 18, his medical records ?protected? him from the woman trying to protect him from himself. About a year later, he committed suicide.
The young men who kill others before killing themselves seek company in their misery, revenge on society, and visibility after a life of invisibility. The shooters faces land the front-page, their names ring in our ears, and they have Wikipedia pages. The coverage not only glorifies the shooters but also advertises massacre as an outlet to the disturbed. In the year following the shootings at Columbine, George Washington High School was closed or evacuated twice because of ?bomb threats.? We were all waiting for a copycat shooting. The suicide rate rose 12 percent following Marilyn Monroe?s death. Those who said there would not be copycats were dead wrong.
A few months after the Littleton shooting, I received a letter from a boy I who I had recently told I wanted to be ?just friends.? He closed the letter with lyrics from the rock group Korn, ?My life is ripping your heart out and destroying my pain.? We are barraged with violence. I am particularly concerned with the violence in video games and movies that we refuse to regulate. Why do we allow savage killing and rape to be conflated with entertainment and then give these as gifts for Christmas? Perhaps because these games can earn as much as $400 million within 24 hours on the market ? .
The summer after the shooting at Columbine, I attended a youth leadership camp where I met a psychiatrist who was called in to train the mental health support team in Littleton before the school was reopened. I walked around the empty building with a small group of adults as the principal pointed to the classrooms and stairwells where students and teachers fell to their death. I was invited to participate in a community building activity that tried to teach the students of Columbine High to be more respectful of people who do not fit in, to expose the fact that everyone is insecure and going through something. It was really powerful.
I knew nice kids from good families who committed suicide or bullied others. The ?geeks? spent hours alone playing games on the Internet such that their only peer interaction was a text message, ?are you ready to watch me kill you?? Technology enhances social networks for those who have them, but it can help the socially isolated to further retreat. A study published this month in Australia found that students who had been involved in cyber-bullying as well as being victimized were two times as likely to have been exposed to violent online games, and nearly four times as likely for those involved in bullying others.
We don?t just need gun control; we need social reform that includes restricting guns and funding mental health services and research. We have very little understanding of these troubled young men who spend months plotting to kill innocent people. We need to re-conceptualize entertainment in the American psyche first by regulating the sale of violent entertainment for astronomical profits. We need to rebuild real communities; those that have been displaced by online communities. I have spent half my life watching kids die in school. Is that how we want to keep living?

MADRID (AP) ? The European Court of Justice is hearing a case that pits Spain's data protection agency against search engine giant Google over the thorny issue of "the right to be forgotten" online.
A Spanish court sought Tuesday's hearing in Luxembourg to clarify if Google is subject to Spanish and European data protection laws.
In the case ? one of many between Spain and Google ? a person found that keying their name into Google shows a newspaper link to a property auction years ago owing to payment failure. The person wants the link removed, which the agency says Google should do. Google believes that's the newspaper's responsibility.
A ruling isn't expected for months.
If it goes in Spain's favor, Google could be made to erase documents people feel violate their privacy.
Yesterday, Samsung announced the HomeSync Android TV box, and as expected that device is making an appearance here on the MWC 2013 show floor. Boxy media hubs can only be so attractive, but the HomeSync's grey-and-black aesthetic is sleek, and the brushed-metal finish will look familiar to anyone who's used a Sammy handset or laptop. There's a pair of USB 3.0 inputs, an HDMI port, optical audio and Ethernet connections on the rear, and buttons for power and settings on the front, but you can easily hide the console deep inside your home theater rig -- it can be controlled exclusively with a Android 4.2-equipped smartphone or tablet.
The Jelly Bean-powered HomeSync runs a 1.7GHz dual-core processor with 1TB of storage, and it supports up to eight accounts for uploading, downloading and sharing content between devices. Those with a Galaxy device will be able to wirelessly stream content to their TVs in full 1080p, and Play Store access is on board for downloading additional media. It worked well during our hands-on, but as with any WiFi-equipped streaming device, there was noticeable lag when mirroring the smartphone display on the connected HDTV. Still, assuming the price is right, we can see this being a solid component within any home theater setup. Take a closer look in our hands-on video after the break.
British study finds a significant drop in hospital admissions for childhood asthma attacks after a law is enacted banning smoking in enclosed spaces.
Mon, Jan 21 2013 at 2:09 PM
A new study in the United Kingdom has some good news for children who suffer from asthma. According to researchers at the Imperial College London, childhood asthma attacks have dropped significantly since a law was enacted in 2007 banning smoking in enclosed spaces.
?
The new study, which was published in a recent issue of Pediatrics, found that the hospital admissions for children suffering from asthma attacks dropped more than 12 percent in the first year after the law was introduced in July 2007. ?The admission rates continued to decline in subsequent years suggesting that the health benefits from the law have had a sustained effect on England's kids.
?
Before the ban was implemented, hospital admissions for childhood asthma attacks were rising at a rate of 2.2 percent per year, with admissions hitting a peak of 26,969 admissions in 2006-07. ?Researchers estimate that the rapid decline in admissions, which began immediately after the law came into effect, is equivalent to 6,800 fewer hospital admission within the first three years after the law came into effect. ?
?
The decline in hospital admissions was seen across the board in both boys and girls and for children living in poor neighborhoods or wealthier communities.?

KANSAS CITY, Mo. (AP) ? The second major snowstorm in a week battered the nation's midsection Tuesday, dropping a half-foot or more of snow across Missouri and Kansas and cutting power to thousands. Gusting winds blew drifts more than 2 feet high and created treacherous driving conditions for those who dared the morning commute.
About 40,000 people in northwest Missouri and northeast Kansas awoke to no power as heavy, wet snow weighed on power lines. Kansas City, Mo., was in a state of emergency as blinding snowfall ? made worst by sustained gusts estimated at 30 mph or higher ? made car and truck traffic too dangerous. About 8 inches of new snow had fallen on parts of the Kansas City metro area as the sun rose Tuesday.
Flights in and out of Kansas City International Airport were canceled, schools, government offices and businesses across the region were closed. City buses were getting stuck.
Numerous accidents were reported in the area, and Mayor Sly James declared the emergency in an unwanted encore to a major snowstorm that dumped nearly a foot of snow on his city just five days earlier. He urged residents to stay home, given that the new storm was expected to dump nearly a foot of new snow on the city.
"This one has the potential to be quite serious," James said.
A strong low pressure system fueled the storm, which also included heavy rain and thunderstorms in eastern Oklahoma and Texas.
The storm knocked power out to thousands of homes in Texas and Oklahoma and was blamed for the death of a 21-year-old man whose SUV hit an icy patch on Interstate 70 in northwestern Kansas and overturned Monday. In Oklahoma, a person was killed after 15 inches of snow brought down part of a roof in the northwest town of Woodward.
In the Texas Panhandle, wind gusts up to 75 mph and heavy snow had made all roads impassable and created whiteout conditions, said Paul Braun, a spokesman for the Texas Department of Transportation. A hurricane-force gust of 75 mph was recorded at the Amarillo, Texas, airport. The city saw the biggest snowfall total in Texas with 17 inches.
Motorists were stranded throughout the Texas Panhandle, with the NWS in Lubbock reporting as many as 100 vehicles at a standstill on Interstate 27.
Schools and major highways in the Texas Panhandle remained closed for a second day Tuesday. State officials said they hoped that stretches of Interstate 40 near the Oklahoma border, which have been closed since Monday morning, would reopen by Tuesday afternoon. Whiteout conditions further impeded efforts to clear roads of more than a foot of snow in western Oklahoma early Tuesday.
Texas Tech's men's basketball team stayed overnight at a hotel in Manhattan, Kan., after playing Kansas State on Monday night, rather try to drive back to Lubbock. Also late Monday, officials with Oklahoma State University announced it would be closed Tuesday due to the weather.
The American Red Cross opened a shelter Monday night in Woodward, Okla., for stranded travelers. It also told its volunteers and workers in Kansas City to be prepared to help in the case of power outages or large numbers of stranded travelers.
Area hospitals closed outpatient and urgent care centers, and the University of Missouri canceled classes for Tuesday. The Missouri Department of Transportation issued a "no travel" advisory asking people to stay off affected highways except in case of a dire emergency.
Meteorologist Mike Umscheid of the National Weather Service office in Dodge City, Kan., said this latest storm combined with the storm last week will help alleviate the drought conditions that have plagued farmers and ranchers across the Midwest, and could be especially helpful to the winter wheat crop planted last fall.
But getting two back-to-back storms of this magnitude doesn't mean the drought is finished.
"If we get one more storm like this with widespread 2 inches of moisture, we will continue to chip away at the drought, but to claim the drought is over or ending is way too premature," Umscheid said.

A new statutory debt ceiling of $2.5 billion should not be taken as an indication that borrowing under the new Government will increase by another $1 billion, Finance Minister Bob Richards insists.
Mr Richards told the House of Assembly that the new ceiling is at a ?realistic? level ? in contrast to the debt ceilings of previous administrations.
?It is the view of this Government that what has become the annual ritual of ratcheting up the debt ceiling gives the impression that there is indeed no debt management plan at all. This is a negative insofar as capital markets are concerned, the same entities we rely on to finance this debt,? he said.
?Therefore, we will be laying legislation, for the approval by Parliament, to raise the authorised debt ceiling to $2.5 billion. It is important to note that this only authorises the limit of Government borrowing, it does not prescribe the actual amount of borrowing.
?We do not expect the borrowing requirement to take us to that level, but we want a level that is pragmatic, realistic and static. The only adjustment to this ceiling I would like to see is an eventual downward adjustment.?
But new rules will be implemented to keep the debt affordable, he continued.
?In conjunction with the new ceiling, the Government commits to keep public debt at such a level that the net debt/GDP ratio does not exceed 38 percent. Additionally, Government recognises the desirability of achieving a net debt/revenue ratio that is below 80 percent and a debt service cost/revenue ratio that is below 10 percent. We will work toward reducing these ratios to such a level over the medium term.?
Mr Richards was reminded at the post Budget press conference that he had harshly criticised former Finance Minister Paula Cox for using debt/GPD ratio as a measure of affordability of the national debt.
But he said other performance measures were being used and Government was not comparing the country to bigger jurisdictions as had the previous administration.
Mr Richards? forecasting envisages a likely ?base case? scenario where debt could rise to just over $2 billion by 2017.
But he warned the debt could end up being as high as $4 billion if corrective action is not taken.
?The most noteworthy of the scenarios is the worst case because it merely extrapolates the current real life deficit and debt trends,? Mr Richards said.
?In other words if we do nothing and economic conditions remain as they are now, Bermuda is forecast to have a public debt of about $4 billion in five years. Debt service is forecast to be in the area of $300 million per year, making it by far the largest Government ?department?. After paying debt service and salaries there would be little left for anything else.
?The base case scenario shows debt continuing to rise to just over $2 billion and declining thereafter. The best case sees debt rolling over faster and being somewhat lower after five years. Again, we are working toward and hoping for the best case but the highest probability scenario, ie the expected case, is the base case.?
Pope Benedict XVI gave his pontificate?s final Sunday blessing from his studio window to the cheers of tens of thousands of people packing St. Peter?s Square, but sought to reassure the faithful that he wasn?t abandoning the church by retiring to spend his final years in prayer.
The 85-year-old Benedict is stepping down on Thursday evening, the first pope to do so in 600 years, after saying he no longer has the mental or physical strength to lead the world?s 1.2 billion Catholics.

But while he has lately looked tired and frail, the crowd filling the cobblestone square seemed to energize him, and he spoke in a clear, strong voice, repeatedly thanking the faithful for their closeness and affection as they interrupted him, again and again, with applause and cheers. Police estimated some 100,000 people turned out.
Benedict told the crowd that God is calling him to dedicate himself ?even more to prayer and meditation,? which he will do in a secluded monastery being renovated for him on the grounds behind Vatican City?s ancient walls.
?But this doesn?t mean abandoning the church,? he said, as many in the crowd looked sad at his departure from regular view. ?On the contrary, if God asks me, this is because I can continue to serve it [the church] with the same dedication and the same love which I have tried to do so until now, but in a way more suitable to my age and to my strength.?
The phrase ?tried to? was the pope?s adlibbed addition to his prepared text.
Benedict has one more public appearance, a Wednesday general audience in St. Peter?s Square.
Benedict smiled at the crowd after an aide parted the white curtain at his window, telling the people, ?thank you for your affection.?
Heavy rain had been forecast for Rome, and some drizzle dampened the square earlier in the morning. But when Benedict appeared, to the peal of church bells as the clock struck noon, blue sky crept through the clouds.
?We thank God for the sun he has given us,? the pope said, sounding cheerful.
As cheers continued in the crowd, the pontiff simply turned away from the window and stepped back down into apartment, which he will leave on Thursday, taking a helicopter to the Vatican summer residence in the hills outside Rome while he waits for the monastery to be ready.
A child in the crowd held up a sign on a yellow placard, written in Italian, ?You are not alone, I?m with you.? Other admirers held homemade signs, saying ?Grazie.?
No date has yet been set for the start of the conclave of cardinals, who will vote in secret to elect Benedict?s successor.
One Italian in the crowd seemed to be doing a little campaigning, hoisting a sign which mentioned the name of two Italian cardinals considered by observers to be potential contenders in the selection of the next pontiff.
Flags in the crowd represented many nations, with a large number from Brazil.
The cardinals in the conclave will have to decide whether it?s time to look outside of Europe for a pope.

Magic Slim performs on July 9, 2012 in Vienne, France.
Blues guitarist Magic Slim died yesterday in a Philadelphia hospital, The Associated Press reports. He was 75, and had been dealing with worsening health problems, his manager said.
Slim, born Morris Holt in Mississippi, helped define the sound of post-war electric blues in Chicago as a younger peer of icons like Muddy Waters and Howlin' Wolf. Slim's first instrument was piano, but after he lost the little finger on his right hand in a cotton-gin accident, he switched to guitar, and also played bass with his mentor, the guitarist Magic Sam. Slim moved to Chicago in 1955, but found it so difficult to land gigs on a competitive South Side blues scene that he soon returned home.
2012 in Memoriam: Musicians We Lost
Back in Mississippi, he developed his talent playing small gigs like plantation parties, with brothers Nick and Douglas as his backing band, the Teardrops. They returned to Chicago by the mid-Sixties, this time for good, and began a recording career in 1966 with the song "Scufflin'," the first in a series of singles that led eventually to his first album, "Born Under a Bad Sign," in 1977. His latest, the covers album "Bad Boy," came out in 2012.?
Though he's most closely identified with Chicago, Slim had lived in Lincoln, Nebraska, for nearly 20 years. His manager, Marty Salzman, said bleeding ulcers sent Slim to the hospital, though he also suffered from heart, lung and kidney ailments.
Fruit flies force their young to drink alcohol -- for their own goodPublic release date: 22-Feb-2013 [ | E-mail | Share ]

Fruit fly study adds to evidence that using toxins in the environment to medicate offspring may be common across the animal kingdom
When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps.
The discovery by biologists at Emory University is being published in the journal Science on Friday, February 22.
"The adult flies actually anticipate an infection risk to their children, and then they medicate them by depositing them in alcohol," says Todd Schlenke, the Emory evolutionary geneticist whose lab led the research. "We found that this medicating behavior was shared by diverse fly species, adding to the evidence that using toxins in the environment to medicate offspring may be common across the animal kingdom."
Adult fruit flies detect the wasps by sight, and appear to have much better vision than previously realized, he adds. "Our data indicate that the flies can visually distinguish the relatively small morphological differences between male and female wasps, and between different species of wasps."
The experiments were led by Balint Zacsoh, who recently graduated from Emory with a degree in biology and still works in the Schlenke lab. The team also included Emory graduate student Zachary Lynch and postdoc Nathan Mortimer.
The larvae of the common fruit fly, Drosophila melanogaster, eat the rot, or fungi and bacteria, that grows on overripe, fermenting fruit. They have evolved a certain amount of resistance to the toxic effects of the alcohol levels in their natural habitat, which can range up to 15 percent.
Tiny, endoparasitoid wasps are major killers of fruit flies. The wasps inject their eggs inside the fruit fly larvae, along with venom that aims to suppress their hosts' cellular immune response. If the flies fail to kill the wasp egg, a wasp larva hatches inside the fruit fly larva and begins to eat its host from the inside out.
Last year, the Schlenke lab published a study showing how fruit fly larvae infected with wasps prefer to eat food high in alcohol. This behavior greatly improves the survival rate of the fruit flies because they have evolved high tolerance of the toxic effects of the alcohol, but the wasps have not.
"The fruit fly larvae raise their blood alcohol levels, so that the wasps living in their blood will suffer," Schlenke says. "When you think of an immune system, you usually think of blood cells and immune proteins, but behavior can also be a big part of an organism's immune defense."
For the latest study, the researchers asked whether the fruit fly parents could sense when their children were at risk for infection, and whether they then sought out alcohol to prophylactically medicate them.
Adult female fruit flies were released in one mesh cage with parasitic wasps and another mesh cage with no wasps. Both cages had two petri dishes containing yeast, the nourishment for lab-raised fruit flies and their larvae. The yeast in one of the petri dishes was mixed with 6 percent alcohol, while the yeast in the other dish was alcohol free. After 24 hours, the petri dishes were removed and the researchers counted the eggs that the fruit flies had laid.
The results were dramatic. In the mesh cage with parasitic wasps, 90 percent of the eggs laid were in the dish containing alcohol. In the cage with no wasps, only 40 percent of the eggs were in the alcohol dish.
"The fruit flies clearly change their reproductive behavior when the wasps are present," Schlenke says. "The alcohol is slightly toxic to the fruit flies as well, but the wasps are a bigger danger than the alcohol."
The fruit flies strains used in the experiments have been bred in the lab for decades. "The flies that we work with have not seen wasps in their lives before, and neither have their ancestors going back hundreds of generations," Schlenke says. "And yet, the flies still recognize these wasps as a danger when they are put in a cage with them."
Further experiments showed that the flies are extremely discerning about differences in the wasps. They preferred to lay their eggs in alcohol when female wasps were present, but not if only male wasps were in the cage.
Theorizing that the flies were reacting to pheromones, the researchers conducted experiments using two groups of mutated fruit flies. One group lacked the ability to smell, and another group lacked sight. The flies unable to smell, however, still preferred to lay their eggs in alcohol when female wasps were present. The blind flies did not make the distinction, choosing the non-alcohol food for their offspring, even in the presence of female wasps.
"This result was a surprise to me," Schlenke says. "I thought the flies were probably using olfaction to sense the female wasps. The small, compound eyes of flies are believed to be more geared to detecting motion than high-resolution images."
The only obvious visual differences between the female and male wasps, he adds, is that the males have longer antennae, slightly smaller bodies, and lack an ovipositor.
Further experimentation showed that the fruit flies can distinguish different species of wasps, and will only choose the alcohol food in response to wasp species that infect larvae, not fly pupae. "Fly larvae usually leave the food before they pupate," Schlenke explains, "so there is likely little benefit to laying eggs at alcoholic sites when pupal parasites are present."
The researchers also connected the exposure to female parasitic wasps to changes in a fruit fly neuropeptide.
Stress, and the resulting reduced level of neuropeptide F, or NPF, has previously been associated with alcohol-seeking behavior in fruit flies. Similarly, the level of a homologous neuropeptide in humans, NPY, is associated with alcoholism.
"We found that when a fruit fly is exposed to female parasitic wasps, this exposure reduces the level of NPF in the fly brain, causing the fly to seek out alcoholic sites for oviposition," Schlenke says. "Furthermore, the alcohol-seeking behavior appears to remain for the duration of the fly's life, even when the parasitic wasps are no longer present, an example of long-term memory."
Finally, Drosophila melanogaster is not unique in using this offspring medication behavior. "We tested a number of fly species," Schlenke says, "and found that each fly species that uses rotting fruit for food mounts this immune behavior against parasitic wasps. Medication may be far more common in nature than we previously thought."

The only obvious visual differences between the female and male wasps, he adds, is that the males have longer antennae, slightly smaller bodies, and lack an ovipositor.
Further experimentation showed that the fruit flies can distinguish different species of wasps, and will only choose the alcohol food in response to wasp species that infect larvae, not fly pupae. "Fly larvae usually leave the food before they pupate," Schlenke explains, "so there is likely little benefit to laying eggs at alcoholic sites when pupal parasites are present."
The researchers also connected the exposure to female parasitic wasps to changes in a fruit fly neuropeptide.
Stress, and the resulting reduced level of neuropeptide F, or NPF, has previously been associated with alcohol-seeking behavior in fruit flies. Similarly, the level of a homologous neuropeptide in humans, NPY, is associated with alcoholism.
"We found that when a fruit fly is exposed to female parasitic wasps, this exposure reduces the level of NPF in the fly brain, causing the fly to seek out alcoholic sites for oviposition," Schlenke says. "Furthermore, the alcohol-seeking behavior appears to remain for the duration of the fly's life, even when the parasitic wasps are no longer present, an example of long-term memory."
Finally, Drosophila melanogaster is not unique in using this offspring medication behavior. "We tested a number of fly species," Schlenke says, "and found that each fly species that uses rotting fruit for food mounts this immune behavior against parasitic wasps. Medication may be far more common in nature than we previously thought."

HILLSBOROUGH, Calif. (AP) ? As if the $100 million asking price wasn't deterrent enough, the owner of a mansion for sale in a ritzy San Francisco suburb says the buyer can move in only after his death.
The unusual arrangement is for a 16,000-square-foot Mediterranean-style home on more than 45 acres in Hillsborough.
The San Mateo County Times reports (http://bit.ly/VyKCcz ) the owner, 76-year-old Christian de Guigne (deh GHEEN-yay) IV, was born and raised in the home and doesn't plan to turn it over to the new owner until he dies.
Sotheby's International Realty agent Gregg Lynn says the arrangement was common for property traded up until the 20th century. He called the estate a once-in-a-lifetime opportunity.
Another home nearby recently sold for $117.5 million.
Police commissioner Riah Phiyega has confirmed the lead detective in Oscar Pistorius' murder investigation has been taken off the case as he is facing seven attempted murder charges for opening fire on a minibus full of passengers. Phiyega said Hilton Botha said had been removed from the case pending an internal police probe. Charges against Botha over the 2011 shooting were initially dropped but the National Prosecuting Authority told Reuters they were reinstated on 4 February, 10 days before Pistorius shot girlfriend Reeva Steenkamp in his Pretoria home. At the time of the taxi shooting, Botha - a detective with 24 years on the force - was chasing a man accused of murdering a woman and disposing of her dismembered body down a drain.
MAGISTRATE QUESTIONS PISTORIUS AFFADAVIT
The magistrate?hearing Oscar Pistorius? bail application has asked why the athlete?s affidavit made no mention of Reeva Steenkamp?s response when he shouted out to her that there were intruders in the house. Pistorius? advocate, Barry Roux, replied that it was ?unlikely? she would have replied, as she was scared. Magistrate Desmond Nair?also wanted to know if it was not possible that Steenkamp had gone to the toilet earlier, and whether there was not a "little" urine in her bladder, but Roux said there was none, adding that Steenkamp had locked herself in the toilet to protect herself from an intruder, and not from Pistorius.
SHARK NETS FOR FISH HOEK BEACH
Fish Hoek beach in Cape Town is set for a year-long pilot project into whether shark nets would be a deterrent to the predators. Fish Hoek is the site of several deadly shark attacks, mainly by great whites. The Cape Times reports that the City of Cape Town will be allowed to install shark nets at beach after the agriculture, forestry and fisheries department approved the permit, which would allow the nets to be in place until January 2014. The report says the nets are different from those used in KwaZulu-Natal, which were designed to kill sharks. The nets at Fish Hoek will serve as a barrier as they had far smaller mesh.
DENEL SCORES AS DEMAND FOR DRONES INCREASES
Denel Dynamics, a division of state-owned Denel, South Africa's biggest maker of defence equipment, is scoring from the demand from unmanned aerial vehicles (UAVs) more commonly known as drones. Sello Ntsihlele, executive manager for UAVs at Denel Dynamics, told Reuters this was "the best time" for UAV sales. Demand is growing fast in developing countries, in the Middle East, the Far East and Africa. The Gulf is critical in all this," he said on the sidelines of the biennial International Defence Exhibition and Conference (IDEX) in Abu Dhabi, capital of the United Arab Emirates (UAE). The company had received up to double the number of inquiries from prospective clients than at the same conference two years ago, Ntsihlele said
QUESTIONS OVER NEW ROBBEN ISLAND CHAIR
The new chair of Robben Island?s museum council, Sibusiso Buthelezi, was the subject of a forensic investigation and had disciplinary action recommended against him while in the employ of the Gauteng provincial government. Buthelezi has strong ties to arts and culture minister, Paul Mashatile, The Star reports. Buthelezi was head of the housing department and Mashatile was the MEC for the same portfolio between 1999 and 2004. Buthelezi was placed on suspension in 2009 when he was Gauteng?s head of public transport, roads and works. Gauteng Premier Nomvula Mokonyane said at the time that Buthelezi ?had contravened or failed to comply with key provisions of the Public Finance Management Act, Treasury regulations and Treasury supply chain management practice notes which have exposed the department to significant financial risk?.
PUBLIC PROTECTOR: CORRUPTION RIFE IN LOW-COST HOUSING
Maladministration and corruption is rife in the low cost housing development sector, Public Protector Thuli Madonsela has told parliament, saying she had already received 5,000 complaints this year. DA spokesman on human settlements, Stevens Mokgalapa, said the ?current crisis in the provision of decent housing to all is robbing thousands of South Africans of the opportunity to improve their lives. Minister Sexwale must act now to bring the crisis to an end?. Madonsela told the portfolio committee on human settlements that a disproportionate number of procurement contracts were awarded to ANC members; bills were received for houses that were not built; and that municipal inspectors failed to issue occupancy certificates that are meant to confirm the quality assurance of houses.
TWELVE MEN ARRESTED FOR GANG RAPE ON MINE
Police in Gauteng have arrested 12 men for gang-raping a woman near Driefontein Number Five shaft in Carletonville. Sapa reports that the victim and a friend were walking home to Mpahla village when illegal miners confronted them. Lieutenant-Colonel Lungelo Dlamini said the woman was hit on the head with a knobkierrie. The men then dragged her behind nearby bushes where eight men raped her. Her friend escaped unharmed. She was then taken to a shack where another four men raped her. The young woman ?sustained multiple injuries on the head, face and body, and was taken to hospital? Dlamini said. The men, from Lesotho, will appear soon in the Carltoneville Magistrate?s Court. DM
Do you want to improve your life into a better one? The following article will help you develop your life.
A very important part to self improvement is an understanding of your life?s ambition. You can perceive life differently if you have set long-term goals.
Are you having trouble finding a difficult time meeting someone that you want to share your life with? Your soul mate might be out there looking online for you right now. Both websites have their advantages and cons.
Identify what is standing in between you and success. Sometimes, this can be a difficult job for you to see on your own. However, being able to identify our weaknesses is the first step to addressing them and ultimately changing them. Take care to eliminate the obstacles that stand between you and the future that you wish to have.
This may sound simple on paper, but for some it is the most difficult.
You should always treat everyone with respect, no matter what power they hold or what they could do for you.The way that you treat them says more about the person that you are.
Sexual capitol is an important new trait undergoing research. This means to use your sexuality to get what you want but rather than your charm. Good social skills are not something everyone has, but developing them help you go the distance in life.
Exercising is not only a way to lose weight. There are many other benefits from regular exercise. As you work out, your body will release chemicals necessary to relieving your stress.
Find books that sooth and encourage you. Some people see it spiritually, while others find that religious text inspires them.
You can teach yourself how to approach tough situations without losing your cool. Take time during your day to stop and take some deep breaths.
Ask others about their accomplishments instead of bragging about your own.
Choose one aspect of yourself that needs improvement, and concentrate on that. Even though you may want to develop several of your personal characteristics, your chances of doing this successfully are greatly increased if you concentrate on enhancing them one by one. Such a process also facilitates lasting improvements to your attitude, because habits that are acquired gradually and deliberately are more likely to be permanent.
Make the important aspects of your life and whether you are still focused on it.
There is no way to have faith without love.Put your faith into action by encouraging charity toward those around you, but yourself as well.
Stress is one of happiness. Stress causes both a physical and an emotional toll on your body. To be able to think clearly, it is critical to banish unnecessary stress from our minds. Set aside time every single day to be alone and clear your mind. Having a time to refresh can make you more peaceful and improve your self-image.
Quit worrying so much. Creating worries is what happens when you expect the worst to happen, before anything has happened. Instead of worrying endlessly about what might happen, start preparing for those scenarios. Being prepared for the worst will help you to stop worrying about it and live normally.
You cannot take care of other people unless you can care for others. No matter how much progress you have made in your personal development, allow yourself time to recover and rejuvenate yourself.
Self-discipline is a key element of any successful personal development plan. Learn to exercise self control over the desires of your thoughts and actions. You can conquer many desires such as lust, greed, overeating and drunkenness.
It does not matter if you have fancy clothing or resemble a super model. Your natural personality will be what matters in the long run. Try and change the inside rather than the outside.
Everyone needs a sweet, salty or starchy treat sometimes. Stress is not good for you. Because of this fact, you shouldn?t worry too much about little things.
You have to choose and consciously decide to work toward it.
Write yourself a little pep talk to yourself.List all of your good qualities on an index card. Keep the card in your purse or wallet, and read through it when you feel your confidence flagging. You can even record yourself reading it or make a video.
Always be on the look for new challenges.You could acquire new understanding of the world and learn new talents. You may even be lucky enough to do something that has done by anyone. Try to find your own niche, rather than following in everyone else?s tracks.
If you are not able to achieve anything you wanted to, it is time to evaluate the situation seriously. Look for resources related to your issues and ask your friends about their struggles. You might discover that your aim is too high, you are missing something, or you are not putting enough into it.

Famous evangelical Christians, like other public figures, have to choose their friends a bit more carefully than the rest of us plebs. In New York Jets' quarterback Tim Tebow's case, this apparently means bowing out of a speaking engagement at a controversial Dallas mega-church where the pastor has, among other things, stated that he believes homosexuality is? a "perverse ... degradation of a person?s mind."?
After the church's high-profile booking raised eyebrows and some media ire, Tebow called First Baptist Church pastor Robert Jeffress on last night to cancel the scheduled April appearance at the church, telling the pastor he "needed to avoid controversy right now for personal and professional reasons," according to Jefferss's interview with the Associated Press. Tebow also tweeted about his change of heart, noting that he'd canceled the appearance "due to new information that has been brought to my attention."
Tebow, arguably more famous at this point for his outspoken faithfulness than for his football prowess, isn't a stranger to the Christian right by any means, though he usually tries to avoid hot-button social issues when he talks about his beliefs. It doesn't look like he's trying to cut ties with other conservative, evangelical institutions that might want to hear him speak (like this sold-out "men's impact weekend" at Liberty University this March).
Notably, the athlete hasn't said whether he disagrees with Jeffress's theology or not. If Jeffress is to be believed, Tebow might not be looking to wash himself of an association with the pastor altogether ? the reverend told the AP that Tebow would like to reschedule an appearance for a future date. On the other hand, the disappointed tweets fired back at Tebow's cancellation announcement from his Christian fanbase indicate that the quarterback needs to stay diplomatic about his retreat from Jeffress. In any case, Tebow is clearly getting the message that an appearance in Dallas right now wouldn't go under the radar.
Jeffress, who has said that Obama's presidency is ?paving the way for the future reign of the Antichrist,? previously made headlines in 2011 when he called Mormonism a "cult" at the Values Voter Summit. He later endorsed Romney for president.
Japanese officials probing the emergency landing of a Boeing Dreamliner said Wednesday that the plane?s battery pack was improperly wired, but added this was unlikely to have caused it to overheat.
A series of problems with Boeing?s next-generation aircraft sparked multiple probes around the world and the grounding of the entire Dreamliner fleet last month after the domestic All Nippon Airways (ANA) flight was forced to land.
Japanese investigators have focused on the ANA Dreamliner?s main lithium-ion battery, which was severely damaged by what they believe to have been a build up of heat that resulted in uncontrollably high temperatures.
Japan?s Transport Safety Board said Wednesday it had discovered that the circuit wiring of the burned battery and another one were connected, even though this is not typical in airplanes.
However, investigators added that the battery system has a system to block a reverse current and it had remained intact so the ?unusual? wiring was an unlikely culprit for the overheating.
Investigators said they would now expand the scope of their search to include the aircraft?s circuit wiring.
?We have been investigating what happened, but as we haven?t got to a point where we can say why it happened yet, we can?t say we?ve made progress,? Norihiro Goto, chairman of the Japan Transport Safety Board, told a press briefing.
The unusual circuit wiring may have affected the digital flight data recorder?s measuring of voltage in the burned battery, investigators added.
ANA and Japan Airlines (JAL), major customers of the aircraft with more than 100 combined orders, have been hit hard by the grounding, slashing hundreds of flights, affecting tens of thousands of passengers.
Research shows shift work has a negative effect on health, relationships, marriages and children, and increases rates of separation and divorce. When partners work different shifts there is often little face-to-face interaction. It becomes difficult to plan any family activities, maintain healthy communication, and sometimes even a regular sex life.
In today?s economy, more and more unemployed people are finding it increasingly difficult to find work. As a result, many people are taking whatever jobs they can find ? even undesirable jobs such as shift work.
Shift work jobs can leave both partners with very different feelings. For example, the partner working the job may experience feelings of guilt regarding being away from the home. They may feel frustrated and ?left out? due to being unable to participate in particular events or family time. This worker also may experience increased stress, feelings of overwhelm, and even irritability due to inconsistent sleep patterns combined with other emotions.
On the other hand, the other partner with more regular hours may experience feelings of loneliness. If there are children or others to be cared for in the home, this partner may feel a greater sense of responsibility and accountability. These feelings may lead to resentment and frustration.
Shift work may not be the ideal way of working or living, but it may be necessary to make ends meet or to keep employment. However, even with all of the negative things stated, there is hope. If you and your partner work different shifts, there are ways to ensure you still maintain a happy and healthy relationship. Consider the following tips:
Call or text during breaks.
This simple gesture will keep communication open throughout the day. If possible, try to keep the conversations light. Avoid talking about things that require more time than you have or that could create negative feelings.
Remember, quality is better than quantity.
You and your partner may not have tons of time to spend together, but you can make the most of the time you have. Set a date or plan a fun activity during your next available time together and make the most out of whatever you do.
Leave little reminders of your love.
Little reminders can come in the form of a note or a simple gift. Leave your partner items in surprising places such as the car, the bathroom, or even the fridge. This will let your partner know that you are thinking of them and leave them thinking of you as well. If you?re not really into notes or don?t have time or money for small gifts, consider completing a chore for your partner. This will show that you are considerate of his or her feelings and willing to pitch in to help in any way you can.
Set aside time for ?business talk.?
When partners have different, hectic schedules there is little time for anything. You don?t want the majority of your time spent talking about serious matters such as finances, household issues, etc. Set aside a specific time to address these issues so the remaining time can be enjoyed to the fullest.
Check in emotionally.
In the chaos of hectic days we can remember to say ?hi? or ask ?how are you?? in passing. We may also get to squeeze in an ?I love you? and ?can you pick up some milk?? We want to make sure that we are checking in with our partners on a deeper level. Take the time to know how your partner is really feeling. As mentioned earlier, each spouse can experience various emotions as a result of their roles. Talk about these feelings and discuss what can be done to help both partners fell more comfortable.
Shift work doesn?t have to be miserable for partners, nor does it have to be a death sentence to your relationship. Relationships take hard work. For partners who have very different schedules, hectic lifestyles, or minimal time to spend together, these relationships may require a little extra work. You may choose to use some or all of the tips in this article or you may choose to use none. Evaluate your relationship, look at your partner?s needs, and do whatever is necessary to keep your relationship healthy. Don?t let shift work get the best of you.

In a surprising but not irrational development on Friday, the Green Bay Packers have released Charles Woodson after seven seasons in Title Town. David Rantisi of Wake Up Its Football (youtube.com/wakeupitsfootball) comments on the tough news for Packers fans.
Feb. 19, 2013 ? A team at the NUS Department of Electrical & Computer Engineering led by Dr Qiu Cheng-Wei has come out with an optical device to "engineer" ghosts. When someone claims he has seen a ghost, the phenomenon may be caused by an optical illusion happening through a wild stroke of nature. But the actual engineering of such a phenomenon is the holy grail of researchers in the field of optical illusions, electromagnetic, and radar detection -- not only because of the thrill and excitement of being able to create a "ghost" but because of the implications it will have in science and applications.
Their research has opened up a completely new avenue for cognitive deception through light-matter behaviour control. This would have wide applications in defence and security. Their findings will also pave the way for the design of new optical and microwave devices such as those for detection and communication. The team will further develop this technique to make larger microwave devices to achieve radar "ghosts" and aircraft camouflage suitable for defence purpose.
Dr Qiu's paper, co-authored with and Dr Han Tiancheng (NUS Dept of Electrical & Computer Engineering), Prof Tie Jun Cui, Dr Wei Xiang Jiang (State Key Laboratory of Millimeter Waves, Department of Radio Engineering, Nanjing), and Prof Shuang Zhang (School of Physics and Astronomy, University of Birmingham, UK), entitled "Creation of Ghost Illusions Using Metamaterials in Wave Dynamics" will be published in Advanced Functional Materials in March 2013.
Their paper reported for the first time, the realisation of creating "ghosts" through optic scattering and metamaterials which are artificial materials designed with properties (which do not exist naturally) built-in. Their device is capable of creating more than one virtual "ghost" image from the actual object. The geometric shape, position and equivalent material properties of these "ghost" images can be pre-designed and controlled -- and are also able to appear in distributed places away from the location of the real object.
Doing a David Copperfield
The scientific community has always been enthralled in the creation of an illusion which can potentially transform an actual perception into a pre-controlled perception. So far, scientists experimenting with metamaterials in "ghosting" do not have much success in changing the perception of the real object, and define where the "ghost" should appear. They can only create one "ghost," in the same location (as where the real object is).
But Dr Qiu's device can create multiple "ghosts." It can also make the real object or person "disappear." The researchers can also determine how the "ghosts" look, taking on a different shape or size from the actual object.
Added Dr Qiu, "As our work solves several major issues associated with "ghost" illusion, we believe it will pave way for future applications of advanced optical illusion, camouflage, and cloaking -- in an interestingly new sense. Our work has enormous potential to enhance our ability to mould, harness, and perceive wave at will. I believe it can stimulate new thoughts of realising something extraordinary that is counter-intuitive."
